Mary is carrying her bags and forgot to pee before leaving home. She feels her bladder so full that it can explode. She cannot hitch a ride. She has to think fast so she goes near the road, and let her pee pour down trough her pants relieving her from her bladder pressure. She examines her pants and she decides she can go with the same pants, even though they are wet, and she goes to the road to wait for a ride again. PA163-1280px
